bjorn 9d84d3907b Font texture is u8;
Originally we made the font texture f16 due to "clamping" of the
distance field, and kept it as floats (but f32 since conversion isn't
automatic with Vulkan) here.  However, clamping isn't really an issue.
You can increase the spread of the font to literally get a wider spread
of the SDF for glows, etc.  Switching to u8 uses 4x less texture memory,
which is significant.

bjorn bac57dc0d2 Add stack allocation to temp allocator;
It can be used to push the current cursor onto the stack, perform some
tmep allocations, and then pop the stack to "free" them all at once.
This can be nice if you're doing some temporary allocations that aren't
going to be needed when the function returns, since it reduces the
amount of allocator growth a bit.

This allocator is meant to be threadlocal eventually, so there are no
thread-safety concerns.

bjorn cbe24f482f Adjust font uvs;
- Padding is automatically computed from spread.
  - Spread increases detail at small sizes.
  - Remove failure cases where padding < spread/2
- UVs are un16x2, making room for color
- Don't center glyphs inside their atlas bounding box
- Cache normalized UVs and update them (for glyphs and vertices) when
  the atlas changes size.
  - Updating the UVs is UGLY and duplicates a lot of code.  It may be
    better to normalize the UVs on the fly, or just re-render the entire
    string if the atlas is updated.

bjorn ef19a334a9 Pass:setSampler;
This is an experimental take on the "default filter" system.  Each
render Pass has its own "global sampler", initialized to trilinear.  The
global sampler will be used by default to sample textures/materials in
shaders.  You can set it to a filter mode or a full Sampler object.  You
can always send your own Sampler objects to Shaders if you want
per-texture sampler settings.  The global sampler is designed to be set a
small number of times per pass instead of on every draw.  Basically,
just do Pass:setSampler('nearest') and draw your minecraft world.

It pretends to be like a pipeline state even though it isn't.
Might be nice for nil to mean "the framebuffer size" which is the default.
